Question

The center of a circle is at (4,-3) and it’s radius is 3 units, which point lie on the circle

Answer 1

Any set of (x , y) whose distance from (4, -3) is 3 units lies on the circle.

Explanation:

To find the distance , use the formula

`distance = √((x_2 - x_1)^2 + (y_2 -y_1)^2)`

If distance < 3, (x, y) lies inside the circle.

If distance > 3, (x, y) lies outside the circle.

If distance = 3 (x, y) lies on the circle.
